Swordedit 3 (Starlight) now has the ability to convert machine tags into machine references. It has not been released.

Lets say you import the door from b30.map into your bloodgulch.map. To put a machine into your map, you would somehow need to create a machine ref and a machine spawn reflexive. I have no idea how you would do this (probably using CE or Hexedit or something).

Not anymore... If swordedit finds a new machine tag, it will ask to convert it into a machine reference automatically. You can simply then click "Create Machine" in swordedit, and it goes from there... The machines will then be visible in your map (swordedit being nice will automatically put two device groups in for you to mess around with!) and operational.

This currently works (ish). I threw this map together by importing bridge tag from sparkys madness scenario, and a door from b30. I had to change a bit in eschaton, but swordedit did most of the work automatically. I did not need to use hexedit or CE. Note: It's a better idea to create one machine, fiddle with in eschaton and then duplicate it. Don't make 100 machines with the wrong settings (like I did lol)

Instructions...
1. Switch to blue team
2. Don't touch any of the machines. On the left side of the base there is no door. Go onto the base.
3. Go to the door near the back of the base
4. Whack it to activate everything
